The duo sparked dating rumours after they were spotted dining at Nick and Toni's in the Hamptons here.

"They arrived late and had to wait for a table, and then were seated outside on the patio. They were casually dressed and seemed to be very comfortable chatting," a source told nypost.com.

They were also seen shopping for groceries at a food market.

Directed by Jake Kasdan, 'Sex Tape' is about a married couple who decide to spice things up and make a sex tape, but are shocked when the tape goes missing soon after.
